Hypermetropia With LASIK Surgery

If you are considering hypermetropia with LASIK surgery in China and would like to get know more information about hypermetropia with LASIK surgery, please complete the inquiry form or email us at info@shmtppp.com

What is Hyperopia?

Hyperopia is known by its more common name, farsightedness. People who are farsighted are able to see fine at a distance, but have trouble with close up viewing, such as is necessary for reading. These people require reading glasses for close viewing to avoid squinting or experiencing fatigue and headaches when trying to view things up close.

Normal sight works when light enters the eye and focuses directly on the retina. In a person with hyperopia the eyeball is too short, so the light ends up focusing behind the retina, resulting in problems with near viewing.

How Can Hyperopia Be Treated?

At one time, hyperopia was only treatable with corrective lenses such as glasses or contact lenses. However, it's now possible to have surgery to correct hyperopia. The most popular procedure used to correct hyperopia is LASIK surgery.

How does LASIK Surgery Treat Hyperopia?

LASIK surgery works by reshaping the surface of the cornea, enabling it to better focus light. The surgeon cuts a flap into the epithelium, the outer layer of the cornea. Tissue underneath is removed, or ablated with an excimer laser. The goal in farsighted people is to create more of a slope in the cornea, making it easier to focus light on the retina.

Is LASIK safe?

In the hands of a good surgeon LASIK is extremely safe if the following criteria are met:

  • Stable hyperopia under 6 diopters. (Hyperopia usually stabilizes at around 16 years of age).
  • Absence of Glaucoma and other eye conditions (which your ophthalmologist should rule out before surgery).
  • Adequate corneal thickness (this measurement should always be performed using a pachimeter).
  • Refractive surgery is not recommended for pregnant women.

Just as any other surgical procedure, LASIK has risks. One out of a hundred persons operated on with this technique has some sort of complication. In almost every case there is a solution to the problem. Severe complications are extremely rare.

How should I prepare for LASIK?

No special preparation is needed for LASIK. Your ophthalmologist should make sure there are no associated pathologies which can interfere with the prognosis. An extensive examination of your eyes including pupil dilation (which will determine the exact degree of hyperopia) should be performed. A topography and pachimetry are mandatory since theses exams show the surgeon the exact shape, curvature and thickness of the cornea. With this data he can plan the procedure and discard pathologies not detected in the initial evaluation.

What should I do during surgery?

LASIK is performed under topical anesthesia (anesthetic eyedrops). No injections or general anesthesia are required. The patient is awake during the procedure feeling no pain at all. LASIK takes about 5 minutes per eye. Once finished, you will go home without need for hospitalization.

During surgery you will be lying on an operating bed specially designed for the excimer laser. The operating microscope is an integral component of the system and will be in front of you at all times. This microscope will continuously generate a bright light. Your face will be covered with sterile drapes and oxygen will be provided under them. You should never touch these drapes. A small device will hold your eyelids open. As the initial cut is performed with the microkeratome you will feel some pressure in your eye. This is due to the suction ring needed to hold the device in place. As the microkeratome creates the flap it must pass directly in front of your eye. For this reason you will not see the light during this step of the procedure. At this point your ophthalmologist will ask you to look at a blinking light inside the laser. At this point you can really help with your treatment: better results are obtained if you hold your head and eye completely still during the laser ablation. Finally the surgeon will put back into place the superficial layers of the cornea and will tell you the procedure is completed. You will occasionally feel cold water over your eye that may even go down your cheek. This is the solution needed to keep your eye properly hydrated.

What should I do after surgery?

It is important not to squeeze your eye the first 5 days after surgery. Normally there will be some foreign body sensation, similar to having an eyelash in your eye. No bandages are required so the patient walks out of the operating room by his own means even though vision will be blurry for 2 or 3 days. Eyedrops will be prescribed for 2 to 3 weeks. Two weeks after surgery you will be able to perform any activity without risk.

Is LASIK the Best Option for Treatment of Hyperopia?

While patients with hyperopia have reported a great deal of success with the LASIK procedure, it is a surgery and patients should consider it carefully. There are many options for sufferers of hyperopia. 30-day extended wear contact lenses can restore vision without the inconvenience of regular contact lenses or an invasive procedure. Individuals should consult with their eye care professionals to determine whether LASIK is the right option.
